To @ZZ whom, t may concern- Be it known that I, JOHN C. EDWARDS, acitizen of theUnited States, and a resident of Brookline, county ofNorfolk, State of Massachusetts, have invented an ImprovementinYarn-Spinning Apparatus, of which the following description, inconnection with the accompanying drawings, is a speciiicatiou,

Vlike'letters on the drawings representing like parts. Y

My invention relates to that type of yarnspinning apparatus wherein the.ring is revolubly mounted on the ring-rail, the ring being rotated withthe traveler after the spinbe hereinafter fully described, and particu-A-larly pointed out in the following claims.

Figure l is a diametral sectional view of a portion of a spinningapparatus embodying one form of my invention, the ring-rail being shownin section. Fig. la is a perspective detail of a part of the buier.shown in Fig. l. Fig. 2 is a. sectional view of another embodiment of myinvention, the bader being made apart of the ring. A l Fig. 3 is asectionaldetail of another modification to be described. Fig. 4 is a topor plan view of a part of the construction shown in Fig. 3. Fig. 5 is asectional detail similar to Fig. l, but with a different form of buffer;and Fig. 6 is a perspective detail of a part of the bader shownReferring first to Fig. l, the ring-rail A, of sheet metal, is providedwith the usual cir- I.cular spindle-aperture A, andthe ring B, co- 45operating therewith, is shown as having a flanged head b for thetraveler t, of usual construction. The .web of the ring is shown as`provided with a depending base b, which extends ,freely into thespindle-aperture, said base being bent to present an external annularrecess or seat b2. i A yielding annular buffer c is mounted in the seatbetween thering-base and the edge of the aperture A in the rail, and invFigs'. l and la theibuffer is shown as a spring-coil convex on itsinner circumference to rest in the seat b2 and havingr the turns ofthespiral bent in or concaved along the outer circumference to presenttwo series of projecting portions c' c?, which straddle the edge of theaperture A. The curvature ofthe seat b2 is slightly greater than thecurvar ure of the adjacent part of the buffer (see Fig. l) to permit alimited vertical or axial play of the ring and also to permit someradial movement thereof. When the spindle is speeded up, the pull oftheyarn on the traveler will rotate the ring, and its axial and radialmovements are limited in a yieldingmanner by the butter, which latteralso maintains the ring in operative position relative to the rail.

In assembling the parts the huler is inverted in the spindle-aperture ofthe rail, and the base ofthe ring is then pushed into place within lthebuer, the latter yielding to permit it.

Referring to Fig. 5, the base d of the ring D is.,provided with anannular recess d to receive the buffer d2, which is in this instancemade as a band ofl corrugated spring metal, alternate bends beingpunched, as atds, to leave projections d4 d5, which extend above andbelow the rail, respectively. Aclearance 4 is left between the loweredgeof the buffer andthe external lip or liange 5 pf the ringbase, whichforms the bottom of the external recess d', permitting limited axialmovement of the ring under the strain of the yarn.

In Fig. 2 I have shown the buier formed as a part ot' the ring itself,and for this pur. pose the web f of the ring has a depending portion f',concave-convex in cross-section and made thin and having several slitsor notches fx extended thereinto upward from its lower outturned edgef2. I prefer to provide an external rib or annular projection f3 .at theto p of the notched portion f', of greater diameter than that of thespindle-aperture A' of thering-rail, land normally the edge f2 is ofgreater diameter than the aperture A. To assemble the ring and rail, thebuler` portion f' of the former is compressed sufficiently to permit theedge j2 to pass through the spin'- xoo l spinning@ when the ringisrevolving, the edge f2 limits its vert-ical or axial movement, while theclearance between the edge of the spindleaperture and the conca-vedportion of lthe buffer perinits radial movement of the ring.

Referring to Figs. 3 and 4, theV ring` B is of I, substantially theconstruction-shown in Fig.

1, its external annular recess or seat b2. re-

spring or c'oil fm; but theoutercircumference of the butler isv shown asseated in an annu- Alar concaved holder-7L, having atl its top alaterally-extended flange h', which is secured to the rail A bylsuitable screws hx, the buffer beingr located below the upper surfaceof' the rail'. -By this' arrangement small vrings can be used with:rails having large spindlejaperture's, and as the curvature ot'.the'recess .portions of the buti'er and ring.

bfi is greater than that of the buer provision is made foraxialand'radial movement of the ring under the `stress of the yarn, .whilesuch movements are limited by the cooperating The lower lip h2 of theholder extends beneath the buffer far enough to support the latter in aneffective manner.

IMy invention' is not restricted to the prev'oise construction andarrangement. shown, as

the same may be modified or rearranged without departing from the spiritand scope of .my invent ion. y

'aperture and means to cooperateA edge-ofthe aperture and limit theradial and Having described my invention, -what I `claim as new, anddesire to secure by Letters Patent, isd Y l. The combination with thering-rail having a circular spindle-aperture, of a revoluble ringmovable radially and axially under the stress of the yarn andextendedinto said aperture, and ayielding means to retain the ring `.ioperative position.

2. The oombinationwith the ring-rail heving: a circularSpindle-aperture, of a revoluble lring vfreely movable under unbalancedstrains' and having its base extended into the with the axial movementsof the rinof.

' 3. The combination with the ring-rail having a circularspindle-aperture, and a revoluble ring having a traveler-race and a basedepending below the top of the. rail, ot yielding means'interposedbetween the ring and the rail to limit movement. of the ring u nder unbalanced strains of the yarn.

4. The combination withthe ring-rail hav'- ing a circularspindle-apertore, of a ring having an external annular recess in itslower portion, and yielding means cooperating with the rail and therecessed` portion of the ring to retain the latter in operativeposition.

5. A'l'sheetme'tal ring-rail havin;T acircular spindleapcrl u re, arevoluble ring: capable of radial movement, and au annular yielding`buffer interposed between the ringand the edge of the aperture'in-therail to limit radial movements of the ring.

"6. Asheet-meta-l ring-rail haringaoireular spindle-aperture, arevoluble ring capable of 'yielding buler interposed between the ringaxial movement of the ring.

7. A sheetmetal ring-rail having` a-c'irc-ular spindle-aperture, areroluble ring capable of radial movement and having an annular seat,and a spring mounted iu said seat and in en gagement with the edge ofthe spindle-aperture.

8. A sheet-metal ri 11g-rail having a circular spindle-aperture, arevoluble ring capable of axial and radial movement and havinganannular, external recess", and a spring,r seated in said recess andhavingr peripheral projections extended above and below the edge of thespindle-apertureto limit the axial movement of the ring. y

9. A sheetxnetal ring-rail having a circular spindle-aperture, arevoluble ring, and yielding annularmeans coperati of thespindleaperture*and connecting the ring operatively with the rail.

In testimony whereof I have signed my two subscribing witnesses.
